[reaction: see text] Furanomycin is a Streptomyces metabolite that substitutes for isoleucine in protein translation. We report a concise and modular synthesis starting from the Garner aldehyde and proceeding in seven steps to furanomycin. The key steps include a stereoselective acetylide addition and the Ag+-mediated cyclization of an alpha-allenic alcohol to construct the trans-2,5-dihydrofuran.
